Harry Reems during his "Deep Throat" days. Born Herbert Streicher, he later became a porno superstud.

The Bronx-born porn star, who earned $100 to bed Linda Lovelace in “Deep Throat,” died Tuesday after a long battle with pancreatic cancer at a Salt Lake City veterans hospital, his pal Don Schenk said.

Reems, the only U.S. actor ever convicted of obscenity, was 65 and had been living in Park City, Utah.

Born Herbert Streicher, Reems grew up on 168th St. and Grand Concourse and dreamed of becoming a legit actor.

Alas, most of Reem’s talent was in his pants. And desperate for money, he parlayed his remarkable physique and sexual stamina into a porn career, starting at age 21.

“I loved sex,” he said later. “I was very promiscuous. And I loved acting.”

In 1972, Reems found himself an extra on the set of “Deep Throat.” When the male lead failed to show, Reems filled the breach, playing the randy Dr. Young opposite Lovelace.

The movie became a blockbuster that turned the obscure actor into a porn superstud. And with blue movies becoming mainstream, the mustached Reems became an unlikely ambassador for a business that was trying to shake off its seedy image.

But while Reems was rising, a Brooklyn federal grand jury was investigating whether the mob got a cut of the “Deep Throat” profits.

Reems was charged with federal conspiracy to transport “Deep Throat” to Memphis — a city he’d never set foot in.

The conspiracy charge was later dropped, but Reems was convicted of obscenity — setting up a legal battle on the limits of free speech.
